After Earth (2013)

In the future on a human-populated space colony, Nova Prime, the S’krell alien race attempts to take it over with creatures called Ursas, which hunt by “sensing” fear. Peacekeeping organization The Ranger Corps defeat them with a fear-suppressing technique called “ghosting”, but not before the Ursas kill Senshi, the daughter of the Rangers’ leader Cypher Raige. Kitai, Cypher’s son, blames himself for Senshi’s death. He trains to become a Ranger like Cypher, but is rejected while applying. Kitai’s mother Faia convinces Cypher to take Kitai on his last voyage before retirement. During flight, however, their spaceship is caught by an asteroid shower, causing them to crash-land on Earth, which the humans evacuated a thousand years ago due to an environmental cataclysm.

Both of Cypher’s legs are broken, and the main beacon for firing a distress signal is damaged. Cypher instructs Kitai to locate the tail section of the ship, which broke off on entry to the atmosphere. Inside is the backup beacon, which they can use to signal Nova Prime. Cypher gives Kitai his weapon, a wrist communicator and six capsules of a fluid that enhances the oxygen intake so he can breathe in Earth’s low-oxygen atmosphere. Cypher warns him to avoid the highly evolved fauna and flora and be careful of violent thermal shifts. Kitai leaves to find the tail section, with Cypher guiding him through the communicator.
